Fórmula
Paint (L) = Surface area / Coverage rate × Number of coats. Cans = ⌈Litres / 5⌉.
Preguntas Frecuentes
How many coats of anti-rust paint do I need?
Two coats are standard for most applications; three coats for highly corrosive environments or submerged surfaces.
What is a typical coverage rate?
Most anti-rust primers cover 8–12 m²/L on smooth metal; rough or pitted surfaces reduce coverage.
